I'm not going to be an opportunist. Such a project is long-term. Mbappé, Kimpembe, Rabiot, Lo Celso and Marquinhos are all young players who will spend a lot of time at the club. Neymar, the club's big star, is still 26 years old.
Or have you forgotten that Cristiano Ronaldo just went to be UCL champion with Real Madrid in his fourth season? Before that it was a failure, since he was hired to win the UCL too and ended up seeing the Barcelona of Pep and Messi dominate the world.
PSG first needs a real technician. Unay is a joke, it was to be fired in the 6x1 game. It also needs a first-class midfield. Jorginho would be an excellent option. You need a left back too. I'd hire Bayer Leverkusen's Wendel.
